Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470294, here are decompositions:

71 + 31470223 = 31470294
73 + 31470221 = 31470294
101 + 31470193 = 31470294
127 + 31470167 = 31470294
151 + 31470143 = 31470294
197 + 31470097 = 31470294
227 + 31470067 = 31470294
257 + 31470037 = 31470294

Showing the first eight; more decompositions exist.
